Updated sample proj to use font awesome from nuget.

-Placeholder for splash screen added.
Lots of fixes...

-Fixed bugs in composition with nested transitions.
-Fixed view model binder with context but no model.
-Fixed bugs in samples.
-Added app animation
-Sample now has splash screen
Fixing a major bug in router activation.

-Router activation is now asynchronous (actually it always has been...I
just forgot that...which turned out to be the source of a number of
bugs.). When using the router call activate and return it's promise from
your shell's activate.
-Streamlined how animations are handled in the composition module.
Some splash screen modifications.
Some router cleanup.

-Simplified mapAuto so that it doesn't parse the route into params and
provide a different type of params object. To use params, you must use
explicit mapping.
-Added routeInfo and router references to the params object that is
passed to activate
-Now passing params to convertRouteToModuleId extensibility point so
that it can create params if desired
Minor improvement to view model guard response interpretation.
Created nuget package metadata.
Adding hooks into the route info creation process.
Updated optimizer builds.
Better icon.
Added icon to media.
Update ios splash images.

-updated nuget version numbers and icon url
Updated nuget package dep versions.
Major restructuring.
Updated nuget metadata with new structure.
Improved invalid route handling.
Update README.md

Added atom feed link
Minor update to nuget metadata.
Re-enabled parameters on auto-routes.

I think this can be useful. I implemented it slightly better this time I
think. The params object passed to the activate method on navigation
will now have a splat property only if additional route paramters were
found. The splat will be an array of those parameters in order that they
appeared. If there are not params, splat will be undefined. This makes
it easy to check and differentiates it from names parameters from an
explicitly mapped route.
Some cleanup in system and slightly optimized logging.
